| CVE-2026-19186 | 1 Zephyrproject | 1 Zephyr | 2026-10-07 | 8.1 High |
| ieee802154_decipher_data_frame() in subsys/net/l2/ieee802154/ieee802154_frame.c computed payload_len = net_pkt_get_len(pkt) - ll_hdr_len - authtag_len without first checking that the received frame is at least ll_hdr_len + authtag_len bytes long. All three variables are uint8_t, so a frame whose payload is shorter than the configured authentication tag makes the subtraction wrap around to a large value (up to 255). The wrapped length is passed unchanged to ieee802154_decrypt_auth() and on to the CCM operation as cipher_pkt.in_len/out_buf_max, with apkt->tag pointing at frame + ll_hdr_len + payload_len. Because the receive buffer is allocated to the exact length of the frame received from the radio driver, the crypto layer then reads several hundred bytes past the end of the packet buffer and writes the same number of decrypted bytes back over it in place. The frame's authentication tag is only verified after this processing has taken place, so no key material, association or prior authentication is needed — a single crafted short frame from any device in radio range is sufficient. Frame validation in ieee802154_validate_frame() does not prevent it: a data frame is accepted with a one-byte payload. The result is an out-of-bounds read and an out-of-bounds write of up to roughly 240 bytes into the adjacent network-buffer pool, corrupting other packets or allocator metadata and typically faulting the target. The out-of-bounds content is not attacker-chosen (it is ciphertext XOR keystream over out-of-bounds memory) and the frame is dropped when tag verification fails, so the primary impact is memory corruption and denial of service rather than information disclosure. Exposure is limited to configurations that enable the experimental CONFIG_NET_L2_IEEE802154_SECURITY option, select a crypto device via CONFIG_NET_L2_IEEE802154_SECURITY_CRYPTO_DEV_NAME, and have established a security session with a level other than IEEE802154_SECURITY_LEVEL_NONE; with security disabled or at level NONE the tag length is zero and no underflow occurs. The fix rejects frames shorter than ll_hdr_len + authtag_len before the subtraction, and adds the matching guard on the transmit side in ieee802154_create_data_frame(). | ||||
| CVE-2026-106509 | 2026-10-07 | 7.7 High | ||
| Backstage is an open framework for building developer portals. Prior to 1.14.6, the @backstage/plugin-techdocs-node package is affected by improper validation of mkdocs theme configuration in techdocs. When TechDocs is configured to build documentation locally or in a container, a user with write access to a registered repository can include configuration values in mkdocs.yml that cause arbitrary code execution during the documentation build process. This issue is fixed in versions 1.14.6 and 1.15.4. | ||||
| CVE-2026-106488 | 2026-10-07 | 8.1 High | ||
| Backstage is an open framework for building developer portals. Prior to 0.4.20, the @backstage/plugin-auth-backend-module-oidc-provider package is affected by improper authentication in the oidc provider. Deployments using OIDC email-based identity resolution with a provider that permits unverified email addresses may allow an authenticated provider user to assume another catalog identity. This may grant access and permissions associated with that user. No direct availability impact is demonstrated. This issue is fixed in version 0.4.20. | ||||
| CVE-2026-106451 | 1 Yawkat | 1 Lz4-java | 2026-10-07 | 7.0 High |
| yawkat LZ4 Java provides LZ4 compression for Java. From 1.7.0 until 1.11.4, net.jpountz.util.Native.load() uses File.createTempFile to create an exclusive temporary .lck file but derives the native-library path by removing the suffix, then FileOutputStream opens that predictable path without exclusive creation, allowing another local user with access to the same shared temporary directory to create or replace the library file before System.load() uses it. Successful exploitation depends on shared-directory permissions, host protections, and winning the race, and can execute native code as the victim; hardened systems may instead cause library loading to fail and fall back to Java implementations. Configurations using a system library, a private java.io.tmpdir, or Java-only implementations are not affected. This issue is fixed in version 1.11.4. | ||||
| CVE-2026-106441 | 2026-10-07 | 7.8 High | ||
| Hydra is a framework for elegantly configuring complex applications. Prior to 1.3.6 and 1.4.0.dev9, Hydra passes Python logging configuration to logging.config.dictConfig() without applying Hydra's target policy to handler class values or formatter, filter, handler, queue, and listener factories. An attacker who controls Hydra logging configuration can therefore select an importable class or factory and cause it to be invoked with the application's privileges, even in versions where instantiate() is protected because the logging path does not use instantiate(). This issue is fixed in versions 1.3.6 and 1.4.0.dev9. | ||||

| CVE-2021-21341 | 7 Apache, Debian, Fedoraproject and 4 more | 19 Activemq, Jmeter, Debian Linux and 16 more | 2026-10-07 | 7.5 High |
| XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is vulnerability which may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. No user is affected who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16. | ||||
| CVE-2020-26217 | 6 Apache, Debian, Netapp and 3 more | 23 Activemq, Debian Linux, Snapmanager and 20 more | 2026-10-07 | 8 High |
| XStream before version 1.4.14 is vulnerable to Remote Code Execution.The vulnerability may allow a remote attacker to run arbitrary shell commands only by manipulating the processed input stream. Only users who rely on blocklists are affected. Anyone using XStream's Security Framework allowlist is not affected. The linked advisory provides code workarounds for users who cannot upgrade. The issue is fixed in version 1.4.14. | ||||
| CVE-2019-5010 | 4 Debian, Opensuse, Python and 1 more | 9 Debian Linux, Leap, Python and 6 more | 2026-10-07 | 7.5 High |
| An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service.

| CVE-2018-14647 | 6 Canonical, Debian, Fedoraproject and 3 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2026-10-07 | 7.5 High |
| Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. | ||||

| CVE-2026-46570 | 1 Tuxera | 1 Ntfs-3g | 2026-10-07 | 8.1 High |
| In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_index_walk_down() in libntfs-3g/index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by reading the special crafted file metadata. | ||||
